Problems solved by technology

[0004] At present, there is no clear and systematic measurement method for the pouring allowance of the tundish, which limits the evaluation of the effect of the new process of slag under the control of the tundish. It is a technical problem to measure the pouring allowance of the tundish, and the cost is low, the operation is simple, and the measurement result is accurate. It is of great significance to reduce the pouring allowance of the tundish in the process of high-quality continuous casting, thereby increasing the yield of molten steel

Embodiment 1

[0039] A method for measuring a tundish pouring allowance in a continuous casting pouring process, specifically comprising the following steps:

[0040] Step 1: After continuous casting pours one time until the last ladle stops pouring, use a ruler to measure the depth of the tundish liquid level to 200mm and stop pouring the tundish, wherein the capacity of the tundish is 30t; among them, the scale size: length L is 20mm, width W is 10mm, height H is 1500mm;

[0041] Step 2, drive the tundish car to one side of the continuous casting pouring platform for natural cooling for 3.0 hours;

[0042] Step 3, after cooling, the tundish is hoisted by the crane in the steel plant to the rail transport vehicle, and then the tundish is carefully and slowly transported to the slag yard by the rail transport vehicle;

[0043] Step 4: Lift the tundish by turning over the tundish mechanism and turn it over 180 degrees, pour out all the solidified steel slag in the slag yard for 20m 2 In a ...

Embodiment 2

[0049] A method for measuring a tundish pouring allowance in a continuous casting pouring process, specifically comprising the following steps:

[0050] Step 1: After continuous casting pours one time until the last ladle stops pouring, use a ruler to measure the depth of the tundish liquid level to 250mm and stop pouring the tundish, wherein the capacity of the tundish is 35t; among them, the scale size: length L is 35mm, width W is 20mm, height H is 1800mm;

[0051] Step 2, drive the tundish car to one side of the continuous casting pouring platform for natural cooling for 4.0 hours;

[0052] Step 3, after cooling, the tundish is hoisted by the crane in the steel plant to the rail transport vehicle, and then the tundish is carefully and slowly transported to the slag yard by the rail transport vehicle;

[0053] Step 4: Lift the tundish by turning over the tundish mechanism and turn it over 180 degrees, pour out all the solidified steel slag in the slag yard for 30m 2 in a ...

Embodiment 3

[0059] A method for measuring a tundish pouring allowance in a continuous casting pouring process, specifically comprising the following steps:

[0060] Step 1: After continuous casting pours one time to the last ladle and stops pouring, use a ruler to measure the depth of the tundish liquid level to 350mm and stop pouring the tundish, wherein the capacity of the tundish is 40t; among them, the scale size: length L is 50mm, width W is 30mm, height H is 2000mm;

[0061] Step 2, drive the tundish car to one side of the continuous casting pouring platform for natural cooling for 5.0 hours;

[0062] Step 3, after cooling, the tundish is hoisted by the crane in the steel plant to the rail transport vehicle, and then the tundish is carefully and slowly transported to the slag yard by the rail transport vehicle;

[0063] Step 4: Lift the tundish by turning over the tundish mechanism and turn it over 180 degrees, pour out all the solidified steel slag in the slag yard for 45m 2 in a...

Abstract

A method for measuring the pouring allowance of the tundish during the continuous casting process, belonging to the field of the continuous casting process; the method is: 1) After one pouring of the continuous casting, stop the tundish pouring when the liquid level depth of the tundish is measured to be 200~350mm ; 2) Cool the tundish naturally; 3) After cooling, transfer the tundish to the slag yard; 4) Pour out all the solidified steel slag and let it stand in the slag yard; 5) Use water cooling to manually inject water into the steel slag in the tundish. Cool down, and then cool naturally; 6) Crush the water-cooled steel slag, and perform all-round manual water injection into the steel blocks and lumpy slag to cool down, and then cool it naturally; 7) After the water is air-dried, crush the steel blocks out of the steel slag After all are sucked out, the mass of the steel block is the pouring allowance of the tundish; the method of the invention can quickly and effectively weigh the pouring allowance of the tundish through a series of systematic operations, and has low cost, easy operation and accurate measurement results. .

Description

technical field [0001] The invention belongs to the field of continuous casting pouring process, in particular to a method for measuring the pouring allowance of a tundish in the continuous casting pouring process. Background technique [0002] The tundish is a device used for the transition of molten steel between the ladle and the crystallizer. The tundish bears the molten steel flowing into the continuous casting ladle and acts as a link between the upper and lower, and plays the role of decompression, steady flow, slag removal, and flow diversion. The tundish is not just a container in production, but has become an important part of clean steel production. The role of the tundish cannot be ignored, whether it is for the continuous casting operation or to ensure that the quality of molten steel meets the requirements. [0003] In the continuous casting production, the slag control in the casting process of the tundish has always been one of the problems that plague the p...
